To all whom it may concern,.-

Be it known that I, .CHARLES STEIN, a citizen of the United States, residing at Akron, in the county of Summit and State of Ohio, have invented certain new and usefullmprovem'ents in Vehicle-Tires; and I do hereby declare the followin to be a full, clear, and exact description o? the invention, such as will enable others skilled in the art to which it pertains to make and use the same.v

My invention relates to wheel rims and tlres, and more especially to pneumatic tires which employ an inner pneumatic tube and an outer shoe for covering, retaining, and protecting the inner tube.

The objects of my invention are to provide a pneumatic tire of the type .set forth whereby the inner tube is completely surrounded by the shoe, is easily removed in porti-on or Wholly for repairs or. replacement, and is cushioned at its inner periphery by the inner portions of the shoe; also, to so construct the shoe, in Vcombination with the Wheel-rim that the said shoe is tightly held in the wheel rim regardless of the mfiation or deflation of the inner tube; also, to provide a construeL tion and combination of partswhich will en tirely prevent creepin of the shoe on or in the rim or flanges; a so, to provide one or both inner contiguous margins or circumferences within the shoe at this part and employing a positive means for securing theshoe to the rim or wheel, which means is removable and adjustable as to tension and in such a manner that it will allow of the removal of one or both edges of the shoe for the purpose of' repairs or replacement of either the shoe or the inner tube, and also to provide a means to keep thc outer shoe or tire from stretching and the inner tube from being pinched.

My invention consists in the features, parts, and combination of parts' hereinafter set forth in the claims.

In the drawings, Figure I is a cross-sectional view illustrating my invention as applied to a Wheel with a ilange and part of a rim and showing in solid lines the tire in lplace and the parts in position to hold the same in place and to keep the same from creeping when in'tlns cond1t1on, and illustrating also indotted lines the relation of thev parts when the side flan e (or part of the same) is removed, also t ie removal of one side of the shoe. 'lhis view also illustrates that the side of theshoe may be removed from-the rim either by removin the side ,flange and loosening the clampingolt or by loosening the clamping-bolt and pulling out the side of the shoe over the rim or the flange. Either method may be used, as found convenient er as found necessary. The same can be said of the modifications illustrated in Fi .II.

lIn Fig. I is also illustrated the antistretc 'ng material formed of rectangular tubing embedded in both inner margins of the shoe.

Fig. II illustrates a modification of my inventlon in which the inner margins of the shoe are provided With tubular antistretehing material, circular in cross section, and in which the rim is formed in one piece and either side of the shoe may be removed by loosening the clamping-bolt.

Fig. III showsa construction in which the meeting faces of the shoe are overla ping or diagonal, one of the marginsbeing he d firmly in or to the wheel-rim by the clamping-bolt,

which passes through the antistretching ma- I terial and outer shoe and also illustrates one of the margins as being wider and having anA overlapping flap to prevent pmching of' the inner tube. In this figure the antistretching material is shown to be solid and tol bev embedded in both margins.` Also the 'rim is shown to be formed with separate removable side llanges. One side of the shoe is shown removed by the dotted-dinos.

Fig. IVv illustrates a modified form of construction in which the rim is solid channel shape, and a wide-headed clamping-bolt employed and one margin broader than the other and the antistretching material embedded in the narrow margin, one side .of the shoe being shown as removed from the rim by dotted lines.

FigV illustrates a modification in which the rim is formed so as to receive annular clamping-bands,which are seated in annular grooves at each side of the rim and are formed so thatthey can be contracted or expanded by means such as shown in FigVII. The shoe may be removed, as shown by dotted lines in Fig. IV.

Fig. VI is an annular cross-sectional view looking at the conti fuous margins and illustrating the overlapping iiap employed to prevent pinching of the inner tube. This figure also illustrates the recesses formed" `in the contiguous meeting edges of the shoe to form the hole for the clampingbolt, which enters both sides of the edges and prevents creep- IOO ing and which is employed when the contire formed with a seatfor the inflatable tube extending the entire distance across the-rim and preferably having an antistretching materia embedded in one side of the shoe or tire, said shoe or tire being held to the rim bya bolt F. This figure also illustrates one side of the tire or shoe resting upon the seat, whichI is formed integral with the opposite side and resting contiguous to the clamping-band at one side and slightly below the seats or recesses D, and may have a flap f to prevent pinching of the inner tube or in any way injuring the same. By this construction it Will be seen that one side of the tire D can be easily and conveniently removed by the removal of the band or ringl C, and thatthe seat beneath the inner tube and upon which said inner tube rests extends the full width of the rim within the channel, forming a continuous seat or cushion for the inner tube G.

' The manner of removing the side of the tire or shoe in this case is to remove one of the rims C by loosening the bolt J, which also loosens the ring C and. slips it over its seat,

thus allowing the side of theshoe or tire to be drawn away from the inner tube, leaving a space for access to the said inner tube and for the withdrawal of the same, if necessary. I have found -thisconstruction a very convenient one, and inasmuch as the pressure within the inner tube tends to keep the loosened part of the shoe or tire in placewhen the ring is tightened there is no danger of the same becomlng detached.

In tires and rims of the type above set forth it is desirable in the first place that the inner tube should be protected also, it is desirable that the protecting-shoe should be so constructed and secured to the rim ofl the Wheel that the inner tube is easy of access for mending and removing also, that the shoe be so secured that it will not creep on the rim; also, that the shoe be mechanically secured to the wheel-rim to withstand all strains inci-` dent to traction, and, furthermore, it is desirable that the tires, including the shoe and inner tube, can be applied in the shortest and easiest manner to the- Wheel and without weakening either the shoe rim or wheel, also' a substantial base for the inner-tube and outer shoe torestfon.. In my construction Iy h ave attained' allot/the above features in a simple land economical. 1`nannfer,. asrfoll'owst*l l 4 A` represents the -wheel-felly, to which issecured a rim of any'I ofthe forms illustrated or of other suitable forms. This rimimayibe e formed, as illustrated in Fig.I,-byformi11g7the f so located andl positioned will .same time prevent t rim B with a side fiange b integral therewith and extending outward, as shown, and formb at the opposite side from b. This is my preferred form of channel or rim; but rims constructed as. shown in Figs. II and IV, formed ofone piece with the rim B, or, as illustrated in Fig. III, formed-of separate side flanges Z and b and band B, or even, as shown in Fig. V, of one piece with the rim Bvso bent as to form a channel B `for receiving the contiguous or meeting margins of' the shoe, and having 'side annulnar seats b b to receive annular clamping-rings C C may be employed, it being only necessary that the shoe be supported at opposite sides at its inner circumference at the margins ofthe shoe.

D represents a shoe which is formed of suitable contour, both outward and inward, to protect and contain an inner inflatable tube G. The shoe D may be formed with or without webbing or inserted woven material; but I prefer that it be formed with said webbing. I also prefer that a non-stretchable material, such as d, be inserted at one or both margins near the point of the contiguous parts. Also the shoe D at its point of joining where the margins meet, as at t2, should be provided with an overlying orlapping flap f, which will prevent the pinching of the inner tube G. The non-stretchable material (i may be of any suitable contour in cross-section, and may be formed of metal or hard rubber or other suitable' material, non-elastic or non-stretchable, which will keep the margins, or one of them, from stretching and render them or'it firm. In Figs. I, II', and III, l have illustrateda non-stret chable material d4 as being embedded in both margins of the shoe, while in Figs. IV fand V, I have illustrated said material as being embedded in one edge or margin only.

l F represents Aa bolt or fastening device which 1s provided with any suitable head and asses through the felly and tire, with the headprestinvupon and binding the innerinternal circumiierence of the shoe D. This bolt F Ina as illustrated in Figs. III, IV, and V, pass irectly through the material of the shoe, Where wide margins areA employed, and when firmly hold the shoe to the rimof the wheel. In this case 'the narow margin (see Figs. III and IV, dotted lines) is'removed either by takin@ the side ange b b off, as illustrated in Figs. I and III, or by loosening and raising the bolt F, as illustrated in Fig. IV in dotted lines. In Figs, I and II the bolt F passes through the linefof juncture or contiguous and meeting ends of the shoe, and for the purpose of'se- 4 curin the shoe to the rim and to avoid creeping o the shoe a portion of each c'nntiguous edge, as at f', is cutaway, thus formingrfthe ho e for the bolts to ass through and atfthe lie tire from creepingi' g a channel by placing a removable flange.

ICO

In Fig. V the rim is formed in one piece with the tire B and having seats or recesses b for clamping-rings C C" In this igur'e the bolt F is also employed for securing the shoe to the rim, and in order to remove the narrow margin the ring C is loosened and taken o or out of its seat. Then this side of the shoe may be removed in the same manner as illustrated in Figs. I, III, and IV; but in order to facilitate this removal it is preferable that the bolt .F be loosened, as illustrated in dotted lines.

Fig. VI illustrates the iiap fand the (position of the bolt F when the contiguous e ges are central, and also illustrates the cut-away ortion of the shoe f which allows the bolt to enter the shoe,which prevents, or aids to pre vent, creeping of the shoe on the rim.

In Fig. VII, I have illustrated my preferred form of device for removing, adjusting, or tightening and loosening the rings C or C', (illustrated in Fig. V,) which consists in forming said rings hollow at their ends and emiloying a screw-threaded bolt J, having a ead j held by a bushing j', within which it revolves, and employing a bushing-nut 7'2, in which the screw-threaded portion of the bolt J works. In order to turn the bolt in either direction, the shank may be made polygonal or have a hole ja provided in its shank.

It will be seen from the above description, taken in connection with the drawings, that my shoe is iirst firmly held within the rim by forming the contiguous edges at the inner periphery of the shoe solid excepting at either ine of division, thus makin a seat upon which the inner tube presses, an ,in addition to the bolt F, holding the shoe within the rim, which also prevents the shoe or tire from creeping. It will also be seen that the bolt F acts, auxiliary to the stiiening and non-stretching material d, to retain the shoe in position and in contour and allow of the easy removal at one or both sides, as the case may be, to gain access to the inner tube.

If desired or found necessary or convenient, the bolt F, which retains or holds the tire to the rim, may be entirely dispensed with, as

the shoe or tire will be retained within itsl channel by other means,and hence While it may be desirable in some cases to employ it as an auxiliary it is not absolutely essential.

In setting forth this invention I have illustrated a number of modifications .of the same,

all embodying my invention; but I do not, therefore, wish to be limited to these modiiications, as they may be departed from and still the invention be incorporated or embodled.

What I claim is 1. A combined shoe and rim, for pneumatic tires, embodying a shoe formed with meeting margins forming a seat or support.

vfor the .inner periphery of the pneumatic tube,

means for securing said shoe to the rim passing through the shoe at or near the meetin margins, 1n combination with an emhedde nonestretchable material located in one or both of the margins, for the purpose setforth. 3. In a vehicle-tire ,the combination with an outer shoeor covering having contiguous annular edges at the base thereof, and a flap carried by one of said edges and overlapping the other of said edges, of a langed rim` in which the base of sald shoe rests, a resilient tube contained within the shoe, a bolt passino' through said shoe, and the felly of he whee and an annular, non-stretchable member embedded in the edge of said shoe.

4. The combination with a Wheel-telly, of a rim having an integral, annular, u turned flange along one of its edges, an annu ar plate secured to the felly opposite said flange and extending above saidv rim, a shoe having contiguous annular edges or margins at the base thereof which lie betweensaid flange and said plate, an annular, non-elastic member emedded in one of said edges, a flap or web carried by one of said edges and overla ping the other of said edges and a retainingolt passing through the base of the shoe, the rim and the Wheel-felly.
